Abstract

The invention provides a double-closed-angle sheet-metal part forming method. The method comprises the steps that a base plate is machined; a left die, a middle die and a right die are machined; the left die, the middle die and the right die are installed on the base plate; die surfaces are machined; a double-closed-angle sheet-metal part is formed; the left die, the middle die and the right die are disassembled; the middle die is drawn out, and the double-closed-angle sheet-metal part is taken out. According to the method, the defects that machining needs to be carried out by using two sets of dies and the maintenance cost is high are avoided, the manufacturing cost of the dies is lowered, the forming procedure of the double-closed-angle sheet-metal part is simplified, the technical difficulty that whole forming can be achieved by clamping the part only once is solved, and the clamping error that the part is likely to install invertedly caused by alternating utilization of the dies is reduced, and the forming quality is improved.

Description

A kind of pair is closed angle sheet metal part forming method

Technical field

The present invention is a kind of pair and closes angle sheet metal part forming method, belongs to the forming processing technology field of product.

Background technology

Two angle sheet metal part that closes is the part relative dual-side of board-like material being bent in opposite directions more than 90 degree aftershapings, and the distance between the bending edge of both sides is less than the width at top, and the angle of both sides bending edge bending is called closes angle.This kind two close angle sheet metal part due to both sides bending edge inside, cause molding difficulty, traditional method processes opposite side bending edge with another pattern again after processing side bending edge with a pattern.It is long that this processing method two close the angle sheet metal part manufacturing cycle, needs two molds.And two the use of mold also easily cause the defects such as part is anti-loaded, location is inaccurate, the accuracy of manufacture is low.

Summary of the invention

The present invention designs for the deficiency existed in above-mentioned existing processing method just to provide and a kind of two closes angle sheet metal part forming method, its objective is to realize that one-shot forming is two closes angle sheet metal part.

Method of the present invention is achieved through the following technical solutions:

This kind of two forming method closing angle sheet metal part, is characterized in that: the step of the method is:

The first step, process one piece of profile and be greater than two base plate (1) closing angle sheet metal component appearance and size, the left module (3) of digital control processing three pieces of metal hexahedron shapes, middle module (4) and right module (5), by left module (3), middle module (4) and right module (5) are placed on base plate (1), mutual docking and make joint face coincide there is no gap, left module (3), the height of middle module (4) and right module (5) assembly should 15mm larger than two height closing sheet metal part both sides, angle bending edge (2), left module (3), the width of middle module (4) and right module (5) assembly should be greater than two distance of closing between sheet metal part both sides, angle bending edge (2), with screw by left module (3), middle module (4) and right module (5) are fixed together from the below of base plate (1) and base plate (1) respectively,

Second step, processing mold profile, by the method for digital control processing, close by two the outer mold surface that profile in the sheet metal part of angle processes left module (3), middle module (4) and right module (5) assembly, this outer mold surface is coincide with two interior profile of closing angle sheet metal part;

3rd step, shapingly two close angle sheet metal component, get the top that panel beating material to be processed is placed on left module (3), middle module (4) and right module (5) assembly, adopt the mode of beaing to close angle sheet metal component along shaping pair of the outer mold surface of left module (3), middle module (4) and right module (5) assembly;

4th step, left module (3), middle module (4) and right module (5) assembly, pull down and connect left module (3), the screw that is connected with base plate (1) with right module (5) of middle module (4), module (4) in first extracting out, again by left module (3) and right module (5) relative movement, upwards can take out and shaping twoly close angle sheet metal component.

The advantage of technical solution of the present invention is: avoid two mold processing, maintenance shortcoming costly, reduce die manufacturing cost.Simplify two molding procedure of closing angle sheet metal part, solve clamped one time part and realize all shaping technical barrier, decrease because mould is used alternatingly the clamping mistake easily causing anti-loaded part, improve Forming Quality.

Detailed description of the invention

Below in conjunction with drawings and Examples, technical solution of the present invention is described in further details:

Shown in accompanying drawing 1, this kind of two forming method closing angle sheet metal part, is characterized in that: the step of the method is:

The first step, process one piece of profile and be greater than two base plate 1 closing angle sheet metal component appearance and size, the left module 3 of digital control processing three pieces of metal hexahedron shapes, middle module 4 and right module 5, by left module 3, middle module 4 and right module 5 are placed on base plate 1, mutual docking and make joint face coincide there is no gap, left module 3, the height of middle module 4 and right module 5 assembly should 15mm larger than two height closing sheet metal part both sides, angle bending edge 2, left module 3, the width of middle module 4 and right module 5 assembly should be greater than two distance of closing between sheet metal part both sides, angle bending edge 2, with screw by left module 3, middle module 4 and right module 5 are fixed together from the below of base plate 1 and base plate 1 respectively,

Second step, processing mold profile, by the method for digital control processing, close by two the outer mold surface that profile in the sheet metal part of angle processes left module 3, middle module 4 and right module 5 assembly, and this outer mold surface is coincide with two interior profile of closing angle sheet metal part;

3rd step, shapingly two close angle sheet metal component, get the top that panel beating material to be processed is placed on left module 3, middle module 4 and right module 5 assembly, adopt the mode of beaing twoly to close angle sheet metal component along the outer mold surface of left module 3, middle module 4 and right module 5 assembly is shaping;

4th step, left module 3, middle module 4 and right module 5 assembly, pull down the screw connecting left module 3, middle module 4 and be connected with base plate 1 with right module 5, module 4 in first extracting out, then by left module 3 and right module 5 relative movement, upwards can take out and shaping twoly close angle sheet metal component.

The middle template 4 of the inventive method freely can be inserted, be extracted in implementation process, extracts rear left template and right template is inwardly slided, thus sheet metal component can directly be taken out from vertical direction.
